Some details:I am playing Minecraft on 1.7.10, using Minetweaker 3.0.10B, Modtweaker 0.9.5 and Thermal Expansion v4.1.2-240.Since there is no crash I didn't add a crashlog...

My issue can be easily reproduced if you try to replace or change any recipe in the Phytogenic Insolator. The seeds will always produce their original crop, even if that seed was also edited by Modtweaker. In the example above, I tried to take a Ferranium which produces Iron Nuggets, and replace the Iron Nugget with anything else. Using the Modtweaker code for Agricraft, it is possible to edit the Ferranium to make it grow whatever I want, but the Insolator will stubbornly use the original recipe.
